1) Worldbuilding Needed: What is Jake a Councilor of? It’s never made clear. The Council of Seven? What is the council of seven? Do they have any power? What are they doing about the Orc aggression? Is there an Orc on the council? What’s his/her position? Is it “All tribes can do what they want, there’s no solid leadership, just tribe leadership”. Is it “I told them to stand down and they won’t listen for some reason” Is it “I support the invasion.” Any other Councilors have stances of interest?
2) There’s no conversation between the source hunters after Esmerelda points you towards Evelyn. Right now, the Source Hunters have no option to decide that they don't believe Evelyn. Okay fine, but they also don't give any indication why they SHOULD believe Evelyn. They just say nothing.
If you don't want to do a dual-dialogue about which (or both) of the Source Hunters believes Esmeralda or doesn't, maybe they could have neutral "Always say" fixed lines about how they "may as well look into her just to be thourough - if only so Esmerelda’s defender at trial can’t claim sloppy work".
3) If you have managed to reach the trap platform in the black cove before first encountering a Star Stone – so you have no way to escape – pop up a message: “Your adventure ends here…” like you get in Choose-your-own-adventure books.
4) When you find the letter from the duke of Ferol, the second person to speak should put on/take off sunglasses before they say “To be fair, it’s hard to find a good rhyme… for murder.” YEAAAAAAAHHHHHH! (This last one is a joke)
